A new video from Oregon Sea Grant (OSG), Sea Star Health: Using Blood Work to Identify Sick Sea Stars, reveals how OSG and Oregon State University created the first-ever blood panel for ochre sea stars to use as a baseline for detecting sick ones. The tool could help aquarists treat them before they succumb to Sea Star Wasting Syndrome, which causes their limbs to fall off.

The cause of the syndrome, which was first seen in the Pacific Northwest in 2013, is unknown. OSU veterinary student Heather Renee Srch-Thaden created the blood panel under the guidance of Dr. Tim Miller-Morgan, an aquatic veterinarian with OSG Extension, and Dr. Susan Tornquist, dean of OSU’s College of Veterinary Medicine.

The video was filmed at OSU’s Hatfield Marine Science Center in Newport, where the public can touch and learn about sea stars in a tidepool exhibit at the HMSC Visitor Center. It was filmed and edited by OSG videographer Vanessa Cholewczynski, with photos by Tim Miller-Morgan and Heather Renee Srch-Thaden.

A research team at Portland State University is conducting a survey of Oregonians to find out how Oregon residents use and value the coast and ocean. The survey asks for your opinions on marine management activities and your preferences for future management. It also includes an online mapping activity, allowing you to indicate places on the coast that are important to you and to recommend changes in the management of areas.

The goal of the survey is to reach a broad set of adult residents who have lived in Oregon for a year or more. The research team also wants to make sure they hear from people across the state, including eastern and southern Oregon.

In Spain, a plate of gooseneck barnacles will set you back more than the cost of a lobster dinner. Known as percebes, goosenecks “set the palate in ecstasy,” a Barcelona chef recently told a reporter. Nevertheless, Julia Bingham winced a little last spring when asked if she had ever tried the tube-shaped delicacies while she was studying them as an undergraduate at Oregon State University.

“I get that question a lot, and it kills me to say ‘no,’” said Bingham, who had gingerly navigated the wave-tossed shore of Cape Perpetua to collect barnacle samples for her University Honors College thesis. “It’s supposed to be sweeter than crab or lobster and taste like the ocean.”

CORVALLIS – Research on the worldwide decline in coral reefs will take center stage at the Corvallis Science Pub on Monday, May 9.

Rebecca Vega-Thurber investigates the microbial ecology of reefs in the Red Sea, the Caribbean and the Pacific and will describe what she has learned about how microbes influence reef health.

“Coral species differ in their susceptibility to bleaching and disease, but these differences are only partially explained by the evolutionary history of corals,” said Vega-Thurber, an assistant professor of microbiology at Oregon State University.

Science Pub is free and open to the public. It begins at 6 p.m. at the Old World Deli, 341 S.W. Second St. in Corvallis.

A new publication from Oregon Sea Grant, Collaborative Science-Stakeholder Engagement, encourages collaboration among scientific disciplines and extending that collaboration to include participants outside the academic world.

The 20-page publication outlines various types of collaboration, both among researchers of diverse disciplines and among researchers and stakeholders. It explores collaborations seeking to achieve different goals in natural-resource research and management (sustainability, climate change adaptive management, decision-making tool development, alternative futures exploration). In also provides examples of stakeholder engagement in these contexts for the understanding and management of various natural resources, and summarizes literature from other research on science-stakeholder engagement elements.

Finally, the guide lists the lessons learned, necessary elements and impacts from these case studies.

The guide is intended as a resource for anyone interested in connecting science producers and science users. It summarizes literature from a broad swatch of research with science-stakeholder engagement elements.

The research was conducted and text written by Laura Ferguson, Oregon State University Marine Resource Management program, with review and contributions by Samuel Chan, Mary Santelmann and Maria Wright.

Collaborative Science-Stakeholder Engagement is available as a free, downloadable PDF here.

CORVALLIS, Ore. – Selina Heppell, an Oregon State University conservation biologist, has been named head of the Department of Fisheries and Wildlife in OSU’s College of Agricultural Sciences.

She is the first woman to hold that position in the department’s 80-year history.

Heppell succeeds former department head W. Daniel “Dan” Edge, who earlier this year was named associate dean of the College of Agricultural Sciences. A faculty member in fisheries and wildlife since 2001, Heppell has served as associate and interim head of the department.

“Selina has provided terrific leadership during her term as interim head of the Department of Fisheries and Wildlife and I am delighted that she will continue to lead the department, which is one of the best in the nation,” said Dan Arp, dean of the College of Agricultural Sciences. “She is a distinguished researcher and teacher with a demonstrated commitment to excellence.”

Heppell will lead one of the largest natural sciences programs at OSU, with more than 600 registered undergraduate majors in Corvallis and online, 180 graduate students and eight degrees and certificates. There are about 140 (non-student) employees in the department, which brought in about $7.4 million in research grants and contracts in 2015.

Heppell has served as principal investigator on several recent Oregon Sea Grant research projects on topics such as the 2012 invasion of Humboldt squid into Oregon and Washington waters and developing better tools for fisheries stock assessment. She also serves on the science advisory board for a successful coastal citizen science project, the long-term Coastal Observation and Seabird Survey Team (COASST).

Oregon Sea Grant will support eight research projects by scientists at three Oregon institutions during 2016-18, on topics ranging from sea-level rise to invasive jellyfish. The grants are funded by the National Oceanic and Atmospheric Administration as part of a biennial appropriation from Congress to Sea Grant programs around the country.

The grants will go to eight principal investigators at OSU, Oregon Health & Science University, and the University of Oregon for research into ocean and coastal issues.

Posted by: admin | November 5, 2015 Comments Off on Port Orford Field Station Holds Open House Nov. 14 |

PORT ORFORD – Oregon State University’s two-year-old research field station in Port Orford will hold an open house Nov. 14 to celebrate its expanded role in coastal research, outreach and education.

The open house runs from 3-6 pm at the station, 444 Jackson Street, in Port Orford. It’s free and open to the public; light refreshments will be served.

The field station is supported by numerous programs at OSU that have a role in marine studies, including Oregon Sea Grant, the Coastal Oregon Marine Experiment Station (COMES), the College of Earth, Ocean, and Atmospheric Sciences, the Department of Fisheries and Wildlife and the OSU Research Office.

Port Orford Sustainable Seafood, a local fish processor, is also located in the building and its staff will be on-hand during the open house to describe its operation.

“The field station has been a place that professional scientists, students and citizen scientists can use as a base of operation to study topics ranging from the ecology of marine reserves to gray whale foraging behavior,” said Cynthia Sagers, OSU’s vice president for research. “The field station provides two laboratories, classroom and office space, and housing for visiting researchers.”

Station manager Tom Calvanese said that in June, the station installed a SCUBA air fill station to support scientific divers conducting underwater surveys. “Recently, we began to make this service available to recreational divers seeking to explore the rocky reefs in the area – a known diver destination,” he said.

Funding for the facility was launched with a $425,000 allocation by the Oregon Legislature in 2011 to purchase the building. OSU has funded its operation since.

The public may not be convinced that ocean acidification is a problem, but a growing number of those who make their living off the ocean have become believers.

A new Oregon Sea Grant-funded survey, being published this week in the Journal of Shellfish Research, found that more than 80% of respondents from the US West Coast shellfish industry are convinced that acidification is having consequences – a figure more than four times higher than found among the broader public, researchers say. And about half the industry people surveyed reported having experienced some impact from acidification.

“The shellfish industry recognizes the consequences of ocean acidification for people today, people in this lifetime, and for future generations – to a far greater extent than the U.S. public,” said Rebecca Mabardy, a former OSU graduate student and lead author on the study.”The good news is that more than half of the respondents expressed optimism – at least, guarded optimism – for the industry’s ability to adapt to acidification.

The mechanisms causing ocean acidification are complex, and few in the shellfish industry initially understood the science behind the issue, said OSU marine ecologist George Waldbusser, who has worked with Northwest oyster growers on mitigating the effects of ocean acidification. However, he added, many have developed a rather sophisticated understanding of the basic concepts of carbon dioxide impacts on the ocean and understand the risks to their enterprise.

“Many have seen the negative effects of acidified water on the survival of their juvenile oysters — and those who have experienced a direct impact obviously have a higher degree of concern about the issue,” Waldbusser pointed out. “Others are anticipating the effects of acidification and want to know just what will happen, and how long the impacts may last.

NEWPORT – Sales of a new starfish-purple ale from Rogue Brewery will benefit researchers’ efforts to study and address sea star wasting disease, a serious epidemic among starfish up and down the West Coast.

As part of a larger effort to learn more about the deadly disease that has devastated sea stars in some places on the Oregon coast, a craft brewery in Newport, Ore., has announced the sale of Wasted Sea Star Purple Pale Ale . Rogue Ales and Spirits planned a celebration today including a beer christening and discussion about the outbreak.

The Rogue Ale brewers plan to donate a portion of the income from sales of this product to support research done by scientists at Oregon State University and and PISCO scientists. More information on Rogue Ales and Spirits’ new ale is available online at www.rogue.com/roguenews

“We are extremely excited about this new partnership with Rogue to raise awareness about the importance of sea stars to healthy ocean ecosystems,” said Bruce Menge, the lead PISCO-OSU investigator. “Rogue’s new beer also recognizes the efforts of investigators across the country who are collaborating to understand this disease and its impacts.”

The brew is described as “light and crisp, with a red or purplish hue and a unique flavor that comes from the purple corn nectar used to brew it.”
